Answer to Problem 1SR

The maximum numbers of employees per store is 105 employees.

The minimum numbers of employees per store is 79 employees.

Explanation of Solution

In the dotplot of number of employees for each of 142 Home Depot stores, the horizontal line represents ‘Number of employees’.

From dotplot, it can be observed that, the maximum or largest number of employees for one of the store is 105 employees. Also, the minimum or smallest number of employees for one of the store is 79 employees.

Hence, the maximum numbers of employees per store is 105 employees and the minimum numbers of employees per store is 79 employees.

Answer to Problem 1SR

The values around which the number of employees per store tends to cluster are 88 employees to 97 employees.

Explanation of Solution

From dotplot, it can be observed that, most of the stores have about 88 to 97 employees. The ‘number of employees for each store’ is clustered around the values 88 to 97, because approximately 75% of the stores are covered under this range.

Hence, the values around which the number of employees per store tends to cluster are 88 employees to 97 employees.
